AddCommandBuffer(CameraEvent. ExecuteCommandBuffer. First at the project we used mesh renderers and it was working all fine when i would use commandbuffer. For example, 3D rendering APIs like Direct3D or OpenGL typically end up constructing a command buffer that is then executed by the GPU. Default); By using fixed buffers it means that render-state changes are minimised between draw calls as the material is not changing and properties that belong to the mesh can be processed seperately by special dedicated fast code for object level properties like vertex data. Under the hood it is not calling SetPass again, and it is reusing the shader pass from the previous draw. Recorded commands include commands to bind pipelines and descriptor sets to the command buffer, commands to modify dynamic state, commands to draw (for graphics rendering), commands to dispatch (for compute), commands to execute secondary command buffers (for primary command buffers only), commands to copy buffers and images Apr 4, 2021 · Synchronization.
